Vadonka talked about an earlyer version of SetCPU with the 2.6.32 kernel. We are talking about 3.0.31 kernel and the brand new 3.0 SetCPU is released today. I think the problem is solved in this version, but I never used this app.

My favourite is the System Tuner Pro. This app is manage the CPU perfectly and show all two core status. How much MHz or offline. I can see if something wrong with second core offline state. (antutu, and maybe the SetCPU not show this) The System Tuner is able to monitoring and record all system log information CPU usage, sensors state, wifi, BT, 3G, etc. and helps to find out the problem reason.

When some sitbag buggy application is communicating with WIFI all night, and use the CPU continously, it able to suck dry the battery until morning.

I wrote to tonyp this last sentece.
[LG Optimus 2x] xtrustkillx:
In standby?
[LG Optimus 2x] brudy:
MisjudgedTwat use the ironkrnL in his build. The ironkrnL is a very outdated, and discontinued stuff. This is the main reason because I never will use such this. This is a matter of principle. I only trust Vandonka's and Temasek's principles and abilities.

Finaly, I'm not impressed from the improvements.
[LG Optimus 2x] kickokim:
I don't use setcpu but I still hàve massive battery drain, I charged the phone all night. This morning it was at 100% , after 4 hours of standby it's at 70%! Wifi and data are off...
[LG Optimus 2x] upetro:
No, not just stand by. I use my phone normaly. That means calling, messaging, ocasional browsing using wi-fi or 3g, some music. But i do turn of data connection and wi-fi, when i am not using them. My batterry life is great with vadonkas kernel. So you guys must be using some apps that eat batterry like crazy.

Oh, and i dont use any programs like setcpu. I just set the 1200mhz overclock in cyanogenmod settings, and i apply the 48mb ramhack. Thats it!
[LG Optimus 2x] jordantr:
If I would turn off 3g then I'm not using it, my battery would hold 2 days. Its sync facebook and gmail, so it consumes lot of battery.
[LG Optimus 2x] Sörnäinen:
Hm hm. Switching to 2G already helps a lot, but it's the display that eats away battery in many cases - so using the phone as a smartphone IS heavy on the battery, and using it as a dumbphone feels somehow pointless to me.
[LG Optimus 2x] mind_challenge:
Since Vadonka is gone, and beta kernels too, can someone please reupload them if he has them? Thanks.
[LG Optimus 2x] skylinegt77:
misjuged twats cm7 based rom is a cm7 kang therefore you can install etana with it. and if you read some posts, you will see that some of your fixes on temaseks kangs were made by misjugedtwat, not saying temasek isnt good coz he obviously is, but we should be more neutral coz every dev work is amazing and not only the big ones
[LG Optimus 2x] temasek:
Again and again u were reminded not to comment such things but u are doing it again.

I would suggest u stop such post, especially in this thread.
[LG Optimus 2x] Najmuddin NP:
Must say there's a need for lot of improvement in terms of battery performance... but for now let's give vadonka a break, he really deserves it :thumbup:
[LG Optimus 2x] skylinegt77:
right now this is the best kernel you can get when it comes to battery, trust me it wont get much better than this, at least in stand by time is the best so far
[LG Optimus 2x] brudy:
My fault. Sorry. We are just try to keep alive the topic until Vadonka come back. :-)
[LG Optimus 2x] skylinegt77:
im not really sure what that was supose to mean but whatever...
[LG Optimus 2x] Najmuddin NP:
But honestly my experience with standby drain is really disappointing when compared to other kernel.

Yea the drain when data was off was really good. (then you could think that the drain could be due to some apps, but that would be same with the other kernel too but that's not case. )
[LG Optimus 2x] skylinegt77:
i see what you mean, i think that means conectivity has to be improved, wi fi and stuff, because i dont use it that much and my phones battery lasts for 2 days, sometimes 3 and i even do play some games + its ocd to 1.4

---------- Post added at 05:06 PM ---------- Previous post was at 04:57 PM ----------

that reminds me, did you make sure you have the correct baseband and matching ril?
[LG Optimus 2x] Najmuddin NP:
No problem with baseband- ril its matching.

Btw how do u resist the urge of not charging and go on for 2-3 days?

I definitely can't..:D
[LG Optimus 2x] skylinegt77:
i dont know, since i got my first phones, i have always been used to not charging them untill they are completely dry and turn off. now when my o2x is dry and shuts off, i turn it back on in cwm mode and wait for its battery to be completely empty XD

i think my battery life being good is due to that and also to that fact the even tho my phones ocd to 1.4 permanently (i never chose a lower freq) my voltage at 1.4 is 1100 mvolts, which from what i heard would make most devices crash, but mine seems to love it, it even gets a small boost in performance when uvd
[LG Optimus 2x] PAIIITET:
where you can download the beta kernel 2012.05.12 ???

1) DS noOC

2) noOC

http://etana.donka.hu/?dir=kernel/3.0.y/beta folder is empty!
[LG Optimus 2x] skylinegt77:
i only have the last beta with oc which is what im using, if some1 tells me how to share it ill gladly do it
[LG Optimus 2x] Najmuddin NP:
Omg :eek: u discharge your battery that badly.. how long have you been using it?
[LG Optimus 2x] skylinegt77:
i have this phone for about 10 months\ 1 year, battery doesnt seem to have any less capacity tho :D
[LG Optimus 2x] Najmuddin NP:
Must say.. u got yourself some kinda superbattery.. :)

Do post a battery drain graph once after 2-3 days usage...
[LG Optimus 2x] skylinegt77:
ok i will try to post it for you in a few days
[LG Optimus 2x] styleage:
kernel only for p990. not support su660 :(
[LG Optimus 2x] mind_challenge:
Can you please share it? Thanks in advance.
[LG Optimus 2x] tonyp:
And why exactly would you do that? It will stay alive with usefull posts, too - or when vadonka gets back anyway.

1.) You know that completely discharging a lithium-ionium battery is like the silliest idea you can have? This is no NiMh battery (and doesnt suffer from memory effect), dont treat it like one. This will actually kill your battery.

2.) performance boost from undervolting? wait what?
[LG Optimus 2x] skylinegt77:
first, i have been treating my battery like that for almost 1 year, second they dont suffer from the memory effect but they do degrade in time, it only takes a lot longer for it to happen, 3rd, i compared results from antutu bench and cf bench, with and without uv, everytime it is uvd it gets around 180\200 more points so i think that means something after u have done it like 10 times and the results are consistent. plus, if you check this, a huge part of your power is lost to heat production, if you can run the same freq at lower voltages=less heat production, in my opinion the boost doesnt come from uv'ing in itself, it comes from the lower temperatures while running, especialy since the phone doesnt heat anything compare to what it did before and you can feel the difference even thru the back

just 1 doubt, how the hell can you kill a battery by discharging it? coz i must have fully discharged mine about hundreds if not thousands of times testing roms, kernels and benchmarks and it never happened
[LG Optimus 2x] :
This is because you can't drain them. Li-ion batteries contain electronic circuitry to prevent unloading them to much. Don't know if this is an arbitrary minimum still best avoided though... Anyway, no need to discharge them completely, this is a 'reflex' from the old days:p

This is a link to my dropbox.

05.16 OC non ds latest beta Etana kernel.

I never share before, if not work I'm sorry.
[LG Optimus 2x] tonyp:
just google it. the first hit I had was this:

http://electronics.howstuffworks.com/everyday-tech/lithium-ion-battery.htm

stating: "If you completely discharge a lithium-ion battery, it is ruined".

It's true whatwas said in this thread, you cannot completely discharge a lithium-ion battery. But if you do it like you and then let it sit uncharged a couple days the probability of it getting "empty" is a lot higher of course. Why take the risk if it doesn't have a plus side?

Did you ever wonder why your 5year old lithium-ion mobile phone won't really work on battery anymore after you charged it? That's because the battery was unused for too long and self-discharged.
[LG Optimus 2x] skylinegt77:
i can confirm that build works coz i have been testing it. so far everything is ok

---------- Post added at 11:58 AM ---------- Previous post was at 11:56 AM ----------

well i certainly wont be doing it again since there is no point, but i wonder why it never died on me XD thanks for the info
[LG Optimus 2x] temasek:
When you first let it totally discharge, it will still have some juice. Probably it still can bootup 1 or 2 times before it completely drained. So what tonyp said is true. Only thing is if its completely drained, there wont be reaction when u press power button when your device is off.
[LG Optimus 2x] Sörnäinen:
I can confirm that this can cause troubles - my original battery didn't get up and working after a BSOD during loading over night. Completely discharged, physically damaged, apparently. Bought a new one.
[LG Optimus 2x] PAIIITET:
surely no one has the beta kernel DS on 2012.05.12??

please share
[LG Optimus 2x] kickokim:
Yes, that one was working great for me too, I regret deleting it!
[LG Optimus 2x] upetro:
Does anyone know what happened to vadonka? Is he just on vacation? Also why are all the beta kernels gone? Weird. I hope all is well with vadonka.
[LG Optimus 2x] Platoon:
Well, i was forced to switch back to 2.6.x kernel (temasek one) because i had wierd slowdowns with may 6 version of 3.x kernel. My sister had even bigger problems. He is making alot of calls and was complaining about phone being unstable (BSODs, restarts,...). I can already tell, that my phone already feels faster with 2.6 temasek kernel.
[LG Optimus 2x] powwow88:
Ye, I'm curious too. He hasn't even posted that: "Guys, I'm going to holiday don't expect me in the next 2 weeks" or something...:confused:
[LG Optimus 2x] vadonka:
hi guys!

sorry for im gone, but i have some serious family trouble with my dad :(

i uploaded a new beta version, fixed the battery drain, so the battery life should be much better. i also do some improvement.

if i have time i will update the op post, here is whats the news:

- screen off max freq OTF part removed, its not working properly, use your favorite cpu control app to manage the screen off max freq

- cpu undervolt part removed from the etana app, also use the third party app for the uv please

- and as i said battery life is greatly improved

im worked on the sysfs controllable overclock like in the jarvis kernel, but i have issues with that. i dont know whats causing this, the jarvis kernel is made for the cm9 but not for the cm7. this project is cancelled for now.

so im alive and working on this project but i need a little time for "fix" things in my real life.
[LG Optimus 2x] skylinegt77:
thats where it gets strange... many times, after rebooting 2 or 3 times to discharge it i would even use an led to further discharge it, and still batterys alive and kicking, idk maybe i was just lucky XD
[LG Optimus 2x] kickokim:
Yeah, you're back!! Does the latest setcpu work for this beta?
[LG Optimus 2x] TrymHansen:
Good to see you back Vadonka, I held off on updating MyrtOTF until I knew you'd be back.

Will the maxscreenoff-frequency return at a later date, or shall I remove it completely for the "new" OTF?
[LG Optimus 2x] slebit:
I'm happy to see that you are back vadonka. And I hope that you will solve the family problems.
[LG Optimus 2x] skylinegt77:
vadonka thanks for everything and good luck with solving your problems, i wish you (and im sure all the other users do too) the best of luck, take your time, settle things straight, when u are back we will still be here waiting 4 u. thanks for everything
[LG Optimus 2x] vadonka:
the screen off max freq kernel based controll is not good, because override the cpu freq in a creepy way, and if some third party app like setcpu, antutu cpu master, etc.. use profiles, it will be problem. not only with the screen off profile, but every other. once the screen is off the kernel based control override everything and this is interfered almost every third party cpu control app. even bsod occured.

so im removing this permanently.

the working otf features, realtime:

cpu on min khz

cpu off max khz

cpu on delay

cpu off delay

gpu freq

vde freq

avp freq

nitro
[LG Optimus 2x] vadonka:
im not planning to leave, just do not exept updates too often. thats all.

this is not the first time when i have problem with my father... i can handle this

please give me a feedback about the today beta.
[LG Optimus 2x] skylinegt77:
right now seems pretty stable. yesterday i was up all night with morfic on gtalk and i managed to change the values of the oc in the tweakaio, problem is they cant be changed on the sys folder, i tried to change them with terminal emulator but it gave me permission denied, then morfic either fell asleep or got tired of trying to explain how to get around this permission to a noob XD
[LG Optimus 2x] vadonka:
changing cpufreq from the sysfs is not supported in my kernel. probably never will be.
[LG Optimus 2x] skylinegt77:
i see... but you probably could do it on a cm9 kernel, right?
[LG Optimus 2x] vkk178:
@vadonka : Hope all is going well . Ps take of ur family first .. kernel can wait .. And all of us can understand . . Best Wishes VK
[LG Optimus 2x] mind_challenge:
Newest SetCPU doesn't shut second core, otherwise everything seems to be good.

edit: Works after reboot. Nice.
[LG Optimus 2x] kickokim:
Ok, latest beta kernel looks like it has less battery drain, but I still have unusable phone after waching video. Strange thing is the phone starts working again if I change brightness from powersave widget...
[LG Optimus 2x] Najmuddin NP:
Yea +1
[LG Optimus 2x] vadonka:
for the cm9, use the jarvis kernel made by Benee. its have the sysfs overclock already.
[LG Optimus 2x] vadonka:
i cant reproduce this issue. please try to pull out some log about this.
[LG Optimus 2x] skylinegt77:
i have been trying to get it but i cant find it anywhere :(

all i could find was a changelog at github
[LG Optimus 2x] kickokim:
Ok, i'm not sure if I did this right... if not i'd like someone to explain how to, please! http://db.tt/BRqrbyMy
[LG Optimus 2x] skylinegt77:
any1 knows where i can get vork kernel jarvis? some1 post a link please if you come across it. thanks in advance
[LG Optimus 2x] ppino:
First of all, good luck with your family problems.

I've got 3 or 4 phone freezing just writing in whatsapp or after taking an 1 minute video, using your 1205161130 and temasek 106. It wasn't overclocked, but undervolted with stock values. After first freeze, unmarked undervolt, and flash kernel again, but problems still there.

Now trying today's beta and no issues for the moment.

Thank you very much.

Sent from an awesome O2X thanks to you all.
[LG Optimus 2x] kickokim:
Also I don't have this issue if I use mx player instead of standard video player. Probably because it uses it's own codecs
[LG Optimus 2x] brudy:
My log is here:

http://db.tt/q3GInyoW

After stop video, and everything is slow down, I just switch off the screen wait a half minute and everything works perfectly again.
[LG Optimus 2x] skylinegt77:
this is just something that occured to me and i dont know if it works coz i dont have that problem with my phone, try downloading quick system info pro from play store, add a task killer widget from that program to homescreen, then when ur done playing the video and your phone is slow, try to hit that button(task killer) and see if anything changes
[LG Optimus 2x] kickokim:
Also charging is very slow...
[LG Optimus 2x] mind_challenge:
Not for me. It charges faster than before. But some problems with OTF Kernel Tweaker application, whenever I reboot values in application are set to minimum.
[LG Optimus 2x] skylinegt77:
i prevented that by going to the files and writing directly in them. try editing tweakaio, if you know what your doing of course :)
[LG Optimus 2x] kickokim:
Ok, charging is back to normal...
[LG Optimus 2x] mind_challenge:
Can you explain how to do it? I tried changing some options in tweakaio with tweakaio app but it didn't help.
[LG Optimus 2x] yarisd4dturbo:
+ 1 ;)

[LG Optimus 2x] tonyp:
Thanks for reporting back, was starting to worry about you Peter.

Take all the time you need, we just needed to know that you're (more or less) okay!
[LG Optimus 2x] vadonka:
thank you!

but im ok, no need to worry :)
[LG Optimus 2x] hadi_rena:
Good to see you again and I hope you can 'fix' your family problem soon :D because family come first IMHO

So we can use newest SetCPU 3.0 perfectly after system reboot ? Second core can be turned off ? If yes for vadonka please update OP. I'll test it later because I'm testing stock kernel right now.
[LG Optimus 2x] Najmuddin NP:
Using the latest beta kernel.. the swype kind of stops working, just like randomly, sometimes its ok for some time and then all of a sudden I can't swype to next screen. Tried rebooting, it will be ok for 4-5 sec and then same problem. it kind of sounds funny but changing of brightness is solving that problem.
[LG Optimus 2x] Najmuddin NP:
Does that happen only after watching a video?
[LG Optimus 2x] lucfig:
Try changing the scheduler. Those with low USB speed try to use BFQ scheduler. This is just a guess.
[LG Optimus 2x] Najmuddin NP:
USB tethering is not working, as soon as I enable it turns to "USB not connected". Anyone else had this?
[LG Optimus 2x] vkk178:
@vadonka : when you get back ps try to fix the USB speed issue
[LG Optimus 2x] hadi_rena:
Known issues if you using kernel 3.0.y
[LG Optimus 2x] fuxmen:
with latest beta kernel two bsods after minute or two of listening music with earphones and screen off, music stops playing and need to pull out battery :/
[LG Optimus 2x] lucfig:
Have you tried the BFQ scheduler?
[LG Optimus 2x] vkk178:
No I haven't tried BFQ , ever since I moved to Vadonka's kernel couple of months back .. IS BFQ giving faster transfer rates with the 3.x kernel ?? As far as I know , SIO and noop were the recommended ones for the 2.x kernel , since BFQ has extra CPU over head .. What about the VR scheduler is it any better ? Thanks

Edit: The new kernel doesnt have BFQ .. only CFQ
[LG Optimus 2x] brudy:
Recently, when the phone is resting in my pocket, I touched my pocket, and my phone was very, very hot. I never felt such heat. Did not respond to the power button. Quickly picked up be the battery, then placed it back on. Thank God booted. The battery lost 40% in one hour. What was that? The second core management work. Everything seems fine, but the phone is still very hot. It's pretty scary. This kernel I'm using:-1205201811-ETaNa_OC 3.0.y.zip. Compcache, on, 1.2 GHz, but now I set to default values​​. No undervolt, no nitro.

The CPU configuration settings of Cyanogen, performance menu, done. This is wrong?
[LG Optimus 2x] kickokim:
Yes, as far as I know. But that's just what i've noticed! Also there is still battery drain, but a lot less than before!
[LG Optimus 2x] Najmuddin NP:
Whenever I reduce the brightness of softkey led lights using touch key lights app the phone's getting really laggy.. anyone knows why?
[LG Optimus 2x] brudy:
When it was happend first time, I was closed all running app manually from running app menu, but changed nothing.
[LG Optimus 2x] powwow88:
Latest beta kernel works well so far.:)
[LG Optimus 2x] brudy:
Newer beta kernels, in the usual place. :-)
[LG Optimus 2x] slebit:
New Beta is working good as always. :)
[LG Optimus 2x] vadonka:
im using the v20q nvrm_daemon binary for now, but in the last few weeks, i tested the v10 (cm default), the v20q and the v20f binary.

the most upd to date rom is the asian v20f, and this version nvrm_binary working great. so i decide that choose this one instead of the v20q.

since the nvrm daemon control most of the core system primary function, its very important that working stable. i hope this binary also can help to rid of the bsod and improve the battery life too.
[LG Optimus 2x] qgtxqj:
is script install.sh right?

cp -f /tmp/system/bin/nvrm_daemon_v10 /system/bin/nvrm_daemon

or should be:

cp -f /tmp/system/bin/nvrm_daemon_v20f /system/bin/nvrm_daemon
[LG Optimus 2x] PAIIITET:
vadonka, please share beta 2012.05.12 DS noOS
[LG Optimus 2x] vadonka:
ooops, thx :)

fixed
[LG Optimus 2x] lineagesum:
im new to etana kernel..

what is the different with DS?

what is Battery Driver for?
[LG Optimus 2x] ppp0941:
i need to press for a long time so that i can scroll and scrolling is very laggy

keyboard is very inresponsive

tested by beta21, no problem with stock kernel
[LG Optimus 2x] brudy:
Cydras: "It's a batery driver with funky battery reading, but the battery life is higher. Because that, on the battery indicator can not be trusted.

I think DS was Debauched Slot or something."

Reginickneo: "The funky reading is because of the driver based on real time battery consumption. If you make a phone call or play games it goes down really fast, and after that it "charge" itself."
[LG Optimus 2x] skylinegt77:
are you guys really sure that it improves battery life? about how much improvement are we talking here?
[LG Optimus 2x] brudy:
I tried once, but I do not think that causes a significant improvement.
[LG Optimus 2x] Najmuddin NP:
Just try changing the brightness once and see if it works..
[LG Optimus 2x] skylinegt77:
idk if this is a smart question, but do we have smart 2nd core management with this kernel?
[LG Optimus 2x] :
Hi, since installing latest beta my phone can't connect to googles servers anymore, be it via Wifi or mobile data. The signal indicator stays white all the time, google play can't get a connection.

Also installed Temasek #107 at the same time, may not even be kernel related... Clearing app data for play store doesn't help. Anything else I can try? Anyone else has the same problem?
[LG Optimus 2x] vadonka:
the battery life improvement mostly while the phone sleep. so the idle time battery consumption is greatly decreased. my phone can hold up for 36 hour and only lost 20% battery.

but, the 3g is still draining the battery very fast, and i cant do anything about that. its because the baseband, ril, or the cm7 fault. but in the cm9 the 3g battery drain also an issue. this is an issue with this phone. the broadband hardware is simply low quality.

the cpu also can drain the battery if its not used correctly. thats why i allow a fully customizable control over that. the default settings is a normal setting, provide a mostly lag free operation but not the best for the battery life.

everything can be adjusted from the etana control app. the undervolt not help too much.

i run many test and compare the battery life with the 2.6.32 kernel and have almost the same result. if you used your phone often every day, you need to charge at every night. its a normal behavior of this phone.

the mighty htc one x have a much worser battery life. i have one of this phone for testing. using the same way like the o2x and sometimes the battery cant even hold up for the night.

smartphone is eat the battery, face it. we can adjust some things for little better battery life, but if you used your phone often, not just for a few calls in a day, your battery will be drained faster.

i try to build a kernel what is fast, smooth, handle the memory better than the stock and have great battery life. but this is impossible :) every positive effect cause a negative side effect...

always have a second option: use the stock kernel.
[LG Optimus 2x] skylinegt77:
i had it with different roms, try re-installing the rom and kernel without wipe
[LG Optimus 2x] brudy:
I have the same problem, but I think this is not kernel problem. Maybe google server problem, or somewhat.
